4 Claims.

This invention relates to new and useful improvements in tile Acuttingand breaking devices especially those of the type described in my priorcopending application for patent,l Serial Number 758,125, which issuedas Patent No. 2,541,708,

dated February 13, 1951.

The machine described in that application comprises a base having anupward extension at one end thereof, a beam pivoted to said extensionand a carriage including tile cutting means slidably mounted on saidbeam. In operation, the tile piece was laid atop said base, the beamlowered thereover and the cutter pushed back and forth across the topsurface of the tile. This device has been found extremely eiiicient incutting tiles of one thickness. However, it often is desired to cuttiles of varying thicknesses, and in such instances it was found thatthe beam, when used with thicker tiles, would rise at one end forming ahalf cut and retain the carriage from being slid the full length of thetile forming a full score line.

The object of the present invention thereof is to provide for verticaladjustment of the pivoted end of the beam to take into account the rangeof tile thicknesses.

Another object of the invention is so to construct the adjustment meansas to provide for the rapid and facile adjustment of the beam and theback stop.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

The tile cutter, with the exception of those parts thereof improved bythe present invention, is substantially identical with that disclosed inmy prior application, Serial Number 758,125, and comprises a box-likebase I5 having end projections or ears I6 through which screws can bepassed for fixing the same .to a work bench or other supporting surface.Extending upwardly from the rear end of the top surface of the base I5,there is a support I1 to which a beam I8 extending longitudinally overthe top of the lbase I5 is pivoted by a bolt I9. According to thepresent invention, the support I1 is adjustable vertically, it is deemeddesirable before describing the adjustment means to completethedescription of the overall device.

The support I1 has upwardly extending projections 2| to retain the beamI8 against lateral displacement and in a rigid manner when the beam islowered onto a tile rested on the top face of the base I5.

In the top of the base, there is a transverse opening 22 through whichthere is extended an elongated gauge bar 23 having indicating grooves orindicia in its top face. The gauge bar is retained in its adjustedposition by a bolt 25 (see Figs. 3, 4 and 5) extending longitudinallythrough the interior of the base I5 and through the end of the same toreceive a wing tightening nut 26.

Interiorly of the base I5, there is provided a transverse member 21,between which and the top of the base, the gauge bar 23 is positioned.Also provided are a second transverse member 28 and a boss 38, both ofwhich serve to guide the bolt 25 and the latter of which serves also foranother purpose to be mentioned hereinafter.v

The gauge bar 23 is formed with an elongated slot 3| through which thebolt 25 is passed, said bolt having a large head for cooperation withthe bar 23 and the transverse member 21. By loosening the bolt 25 thegauge bar 23 can be adjusted to the proper setting.

. On the gauge bar 23, at one side of the base I5, there is an upwardlyextending square 32 for receiving the corner of the tile. This squarehas a protractor portion 33 with an arcuate slot 3Q therein, throughwhich is extended a tightening bolt 35. The square 32 can, accordingly,be adjusted to any angle so that the tile engaged therewith can be cutdiagonally at any desired angle.

At the end of base I5, adjacent the free end of beam I8, is anadjustable stop 36, with a knurled locking nut. This adjustable stop issupported in the boss 3U, and will prevent the cutter which is carriedon the beam I8, in a manner to be described hereinafter, from hittingthe base I5 and marring the cutting edge when scoring and breaking thetile. A stop 31 is provided to prevent the cutter carriage from runningoff the beam, said stop being held in place by a bolt 35.

The cutting element or wheel 40 (Fig. l) is journalled on a pin 4I in asupport 42 depending from a cutter carriage 43 slidably mounted on thebeam I8. Carriage 43 is in the form of a box having slots in either endto admit beam Iii, the box being closed by a cover 49 (Fig. 7). Bearingrollers G2 are provided in the box, said rollers being located above andresting on the beam I8 to ensure smooth gliding movement of the carriageon the beam and prevent wearing out of the beam I8 and the carriage 43from direct metal tometal frictional contact.

'I'he bearing rollers 62 are located in each end of the top portion ofthe carriage 43 above the beam I3 and each is comprised of an inner race62a and an outer race `52h (see Fig. 7) with ball bearings 63 betweenthe races. Each of the rollers 62 is rotatively supported on a spindle54 having one end projected into a complementary recess in the adjacentwall of the carriage 43. That one end of spindle 64 is formed with aprojecting fiange 65, between the inner race 52a and the wall of thecarriage 43 for holding the outer race 552i out of frictional contactwith the wall of the carriage 43 to be freely rotatable. The other endof the spindle S4 is received in a complementary recess formed in theinner wall of the cover 4S and positioned on that other end of thespindle between the roller 52 and the cover 49 there is a split washer65. The split washer has a diamn eter slightly less than the diameter ofthe inner race 5211 and the arrangement is such that the washer 65 iscompressed between the inner race 62a and the cover 49, when the coveris mounted in position, for causing the inner race I52a to befrictionally gripped between the adjacent faces of the flange 55 and thesplit washer 5B to retain the inner race 52a against rotating on thespindle 54. However, the outer race 52D will be free to rotate on theballs 53 relative to the inner race (i2a as the carriage 43 is pushed onthe beam I3.

The construction is such that a tile is placed on the top of base I5,the beam I8 lowered to bring the cutting wheel 4I! into contact withsaid tile and the carriage 43 pushed to and fro en the beam. The cuttingwheel thus cuts a line through the surface of the tile, thereafter, thetile piece is lifted and disposed withinV the breaking device wherein itwill be divided into two parts. This breaking device comprises anadiu'stable support 44 disposed near the upright sunport I 'I andbeneath the beam I8 and having'a locking nut 45 to retain an anvil-likehead 4S thereof in elevated or adjusted position. On the beam I8 thereis a transversely extending member 4'!A see TFigs. l to 3, havingseparated upwardly extending portions 48 by which the same is pivoted bymeans of a pin 553 to the beam I8. Within the bottom surface of member4'! there is a longitudinally extending groove 5I- aliene-d with and ofgenerally the same curvature as the anvil head 46. Accordingly, when thebeam is brought down over the tile Ywhich is then resting on the anvilhead 46, great pressure will be applied to the top surface of the tileso as to apply pressure to opposite sides of the line cut therein. Whensufficient pressure has been applied the tile will snap into two partsand a clean break will have been effected.

The machine as thus far described extremely eflicient for breaking tilesof the same thickness but some diicultv is encountered when it isdesired to break tiles of varying thicknesses.

To overcome this diiculty the invention provides for adiusting theheight of the beam i8 above the base I5 for tiles of variousthicknesses.

To this end the upright support I? is nut .Sf

cured to the base I5 but rather to a post 52 by means of a pin 53, seeFig. 6. The post 52 is slotted below the support II to receive a guideplate 54 extending longitudinally of the base I5, and being slidablymounted in a boss 55 of the base I5. The plate 54 and post 52 aresecured together, preferably by a force t of the former in the slot inthe latter. The boss 55 extends rearwardly of the base I5 and is slit tothe rear edge thereof. The portion of plate 54 extending beyond the baseI5 is provided with a vertical slot 56 through which a bolt 5'I (seealso Figs. l and 2) is passed, said bolt also passing through theprojecting portions of the boss 55. rThe projecting end of bolt 51 isprovided with one or morewashers 58 and is threaded into a crank-nut `60having a handle 6I (Fig. 2).

The construction is such that by loosening nut 6I)-` through handle 6I,the post 52 and plate 54 can be slid up or down to adjust the beam I8 tothe size tile to be cu-t and broken. When the nut 60 is` again tightenedon the bolt 5l the post 52 and' plate 54 are secured in their adjustedposition by compressing the projecting portions of boss 55 together.

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
